Photometrical Method

Milk acetone determination by the photometrical method after microdiffusion and via FT infra-red spectroscopyMilk acetone (AC) and betahydroxybutyrate (BHB) are important indicators of the energy metabolism of cows (ketosis occurrence) and an effective method for their determination, with reliable results, is of great importance. The goal of this work was to investigate the infrared method MIR-FT in terms of its calibration for milk AC and to develop a usable procedure. The microdiffusion photometric (485 nm; Spekol 11) method was used with salicylaldehyde as a reference (Re) and mid infrared spectroscopy FT (MIR-FT: Lactoscope FT-IR, Delta; MilkoScan FT 6000, M-Sc) as an indirect method. The acetone addition to milk had no recovery using MIR-FT (Delta). The reference AC set must have acceptable statistics for good MIR-FT calibration (M-Sc) and they were: 10.1 ± 9.74 at a geometric mean of 7.26 mg l-1, and a variation range from 1.98 to 33.66 mg l-1. The AC correlation between Re and MIR-FT (Delta) was low at 0.32 (P>0.05 but the Log AC relationship between Re and MIR-FT (M-Sc) was markedly better at 0.80 (P<0.01). The conversion of >10 mg l-1 as an AC subclinical ketosis limit could be > -0.80 (feedback 0.158 mmol l-1 = 9.25 mg l-1) and > -1.66. This could be important for ketosis monitoring (using M-Sc).

<p><em>Introduction section is the first section of the thesis that has an important role which summarizes background information about the topic. The ability to write a clear and concise introduction section of a thesis is indispensable skill to writers; thus it is essential for students to be aware of linguistic aspects of writing. Past literature in writing studies have shown that although many studies have been written about the grammatical errors and mistakes in writing, there is very little research done on grammatical problems in writing introduction section of thesis. This research was a descriptive qualitative research which aimed to analyze grammatical problems found in the introduction section of thesis written by English literature students at STIBA Persada Bunda Pekanbaru. The source of data in this research was documents taken from students’ thesis. The data were collected by using coding sheets. The findings of this research showed that the most common grammatical problems found in introduction section of thesis was incorrect verbs which dominated by tenses confusion and lack of subject and verb agreement. The possible solutions to overcome students’ grammatical problems were using indirect method in teaching grammar and prioritizing grammar structures to teach.</em></p>
